Querrey shocks Djokovic at Wimbledon

NOVAK Djokovic is now unsure about whether he will go to the Olympic Games in Brazil after a shock defeat to American Sam Querrey at Wimbledon.

With rumours that he was struggling with a shoulder injury, the world No.1 lost the third-round clash 7-6 6-1 3-6 7-6 after returning to No.1 Court following the previous day's rain delay.

Djokovic confirmed that he would not play in Serbia's Davis Cup quarter-final against Britain in Belgrade, which begins in 13 days.

He was then asked whether next month's Olympics would be his next competitive appearance.

"We'll see," he said. "I have to think about it."

The 29-year-old, looking for a calendar year grand slam and looking to stretch his unbeaten run at majors past 30, appeared to have some physical difficulties against Querrey and when asked if he was 100% fit, he replied:

"Not really, but this is not the place and time to talk about it."

This was Djokovic's earliest defeat at a grand slam since 2009. It was also his earliest loss at Wimbledon since 2008.

He had looked decidedly off-colour on Friday, when he lost the second set in just 22 minutes, but when they resumed just after midday he looked more like his old self. He quickly won the first four games of the third set, only for rain to start falling again.

When they returned nearly two hours later Djokovic looked less assured. He was broken when he served for the set at 5-1 before completing the job at the second attempt two games later.

In the fourth set the momentum tipped one way and then the other. Both players successfully defended break points before Querrey dropped serve at 4-4. However, the American hit back immediately as Djokovic, serving for the set, netted a volley on break point.

The set had been interrupted by a brief rain break at 1-1 and a longer interruption followed after Querrey held serve to go 6-5 up. The two men returned to the court an hour later, upon which Djokovic held serve to force a tie-break.

Djokovic went 2-0 up in the tie-break, but Querrey held firm. Trailing 2-3, the American won a 22-shot rally - the longest of the match - on the next point. At 4-5 Djokovic hit a forehand long. The Serb saved a first match point with an ace but on the second he put a forehand wide, upon which Querrey leapt into the air in celebration.
